The excellent matrix is formed through full fermentation.
Fermentation plays a central role in creating nutrient-rich soil matrices, and there are several methods used in the process. One traditional method is the stacking technique, commonly applied during composting, which can be either aerobic or anaerobic depending on the setup. Another approach is pyrolysis, often used for waste management, while fermentation tanks are mainly used for odor control. Among these, the most widely adopted method is rapid fermentation, also known as microbial-assisted fermentation. This method involves adding specific bacterial cultures, such as Golden Baby, to accelerate the process. Compared to other techniques, it offers better efficiency, lower costs, and improved results, making it ideal for large-scale or commercial production. Fermentation strains used in this process include products from Japan and South Korea, as well as domestic brands like Kinbara, which are well-regarded in the industry.
Substrate fermentation is a complex biochemical process that leads to significant changes in various parameters. The ideal carbon-to-nitrogen (C/N) ratio during fermentation typically ranges between 20:1 and 30:1. However, many organic materials like bark, sawdust, and husks often start with a much higher C/N ratio—sometimes over 150—and require adjustment before fermentation. Moisture content should be carefully controlled at 60% to 70%, and proper aeration through turning or mechanical mixing is essential to support microbial activity.
During the fermentation process, temperature gradually rises from low to high, then stabilizes at a moderate level before dropping again. Initially, the pH is slightly acidic, but it increases as the process progresses. The electrical conductivity (EC) value also rises initially and then slowly decreases by the end of fermentation. Microbial populations evolve throughout the process, starting with mesophilic bacteria, followed by thermophilic fungi like Trichoderma, then actinomycetes, and finally fungi.
To achieve high-quality results, it's crucial to use reliable microbial agents, such as Goldfish microbial fermentation agents, and follow proper procedures. Different strains may significantly affect both the cost and the final outcome, so selecting the right one is key to successful substrate production.
